Rubio and Cruz in the past week have ratcheted up their attacks on Trump as they fight to stay competitive beyond Super Tuesday, when roughly a dozen states will cast votes in the Republican race. Rubio, once intent on bringing down Cruz, notably shifted toward a Trump-take-down strategy during Thursday night’s Republican debate.

“They got together and said, 'Oh, we have to be tough,'” Trump said, mocking his rivals, Rubio and Cruz. “The last debate — did you see them shaking hands? Behind my back shaking hands? They’re high-fiving each other inside before the thing.”

Despite the double team, as Trump called it, “every single poll has Trump winning the debate.”

Trump peppered references to Rubio and Cruz throughout his stump speech, but he also looked beyond the Republican primary, pledging to campaign in blue-state New York and predicting a victory there secures a win in the general election.

“Republicans have a hard time, because structurally you have to win Pennsylvania, you have to win Ohio. You know, they have like a map of, in particular, six states, and you lose one, it’s over,” Trump said. “The Democratic ride is a much easier ride, but if I pick up New York or if I pick up Michigan, it’s over, folks. It’s over.”

Trump said his campaign will do well with minority voters, insisting people will be surprised. “We’re going to do great with Hispanics,” he declared, and “phenomenally with the African-Americans.” His proclamations came as Trump is embroiled in fresh controversy over his reluctance on Sunday to disavow the Ku Klux Klan and white supremacist leader David Duke during an interview.

The billionaire has sparked a record number of voters in the Republican primary en route to a trio of consecutive double-digit margins of victory in New Hampshire, South Carolina and Nevada.

Hillary Clinton on Saturday walloped Bernie Sanders with a 47.5-point victory in South Carolina. Trump said Sanders “took a big beating,” but bragged about the Republican voter turnout in the state the week before.

“I drew, and the Republicans, drew so much more, so many more votes — like double,” Trump said. “And they went down because there’s no enthusiasm for Hillary. None. We went way up because whether people like me or not, there is enthusiasm — that I can tell you.”
